Interesting. In the comics, Blue K has no effect on Superman, but it hurts Bizarro in the same way that green K hurts Clark. (In the comics, blue K was an imperfectly duplicated version of green K.)
Kryptonians appear to be telepathic even when they are non-super; I would imagine that Zara would be able to find Kal-El by mind linking with him.
